GF30.20-P-2100V Component Description For The CC [TPM] Switch,







The CC [TPM] switch is located at the top left of the steering column module (N80).

Task
The CC pushbutton switch switches the cruise control functions, Distronic (with Distronic) and variable speed limitation (except (USA)) on and off.

Function
When the cruise control pushbutton switch is operated, two switching contacts are always activated simultaneously. The actual input takes place by closing the switching contacts (storing the speed). The safety contact must close simultaneously so that the input is accepted.

The shift signals from the CC pushbutton switch are detected by the steering column module and transmitted to the CAN data bus.

For Distronic (DTR)
The Distronic control unit (N63/1 up to 06/2004 and A89n1 as of 07/2004) evaluates shift signals for operation of Distronic and sends corresponding signals for speed limitation to the ME-SFI [ME] control unit (N3/10).

Up to 05/2005
The ME-SFI [ME] control unit evaluates shift signals for operation of cruise control and variable speed limitation (except (USA)).

From 06/2005
The ESP control unit, ESP and BAS control unit or ESP, SPS [PML] and BAS control unit (N47-5) evaluate the shift signals for operation of cruise control and variable speed limitation (except (USA)) and send corresponding signals for the purpose of speed limitation to the MESFI [ME] control unit.
